PRINTING-TELEGRAPH.

SPECIFICATION forming part of Letters Patent No. 290,613, dated December 18, 1883.

Application filed July 19, 1883. (No model.)

T at whom it may concern Be it known that we, \VM. B. VANSIZE, of the city of Brooklyn, Kings county, State of New York, and CHARLES L. BUOKINGHAM, of the city, county, and State of New York, citizens of the United States, have jointly invented certain new and useful Improvements in Printing-Telegraphs, of which the following is a specification.

The object of our invention is to provide a new and improved means whereby a series of. instruments in a circuit may be brought to unison.

The arrangement of a printing-telegraph instrument in connection with which we have shown our device consists of two type-wheelsonebearing letters and the other figuresfirmly fixed to a shaft having a constant tendency to rotate imparted to it by any suitable motor such as a weight, cord, and train of gearwheelscontrolled by an electromagnetic escapement located in an electrical circuit. In a second circuit is an electro-magnetic impression device. Means are provided whereby either type-wheel may be printed from at pleasure, and means must also be provided whereby at the pleasure of the transmittingoperator all the instruments on a circuit or on several circuits operated by one transmitter may be automatically brought to unisonthat is, to simultaneously present the same character at a predetermined point.

To the end of affording means whereby the type-wheels may be brought to unison, we

55 provide an electro-magnetic type-wheel escapement operated by making and breaking the type-wheel circuit. Inthe same circuit is a slow magnet-that is, one which, by reason of its length of core and resistance or pcculiarity of construction, will magnetize and demagnetize more slowly than the type-wheel magnets, and which will not respond to makes and breaks which are of sufficient length only to influence the type-wheel magnets. Upon 'the type-wheel shaft is firmly fixed a radial arm. The armature-bar of the slow magnet normally projects into the path of the said radial arm and looks with the radial arm when said arm has reached that point in its rotation where the type-wheels are at unison. This armature-bar is, however, suddenly moved out of the path of the radial arm once every rotation of the type-wheels by a prolonged impulse of electricity of sufficient duration to 'magnetize the slow magnet, and this move- 5 ment of the armature-bar occurs at the mo ment when the type-whcels should be at unison, so that in case the wheels are in unison the radial arm will not be caught; but in case any type-wheel is out of unison it will be caught and held until the recurrence of such sudden movement, when it will be released and may continue its rotation.

For the purpose of illustration we have shown in a second circuit the means for taking an impression from either type-wheel at pleasure, described in United States Letters Patent No. 126,535, May 7, 1872.

Referring to the accompanying drawing, on is an electromagnet of ordinary construction, preferably having short slotted cores and responsive to short pulsations of electricity.

1 and 2 are two type-wheels, upon the peripheries of which are figures and letters, respectively. They are fixed to a shaft or arbor, b, to which a constant tendency to rotate is imparted by a weight and train of gearwheels of well-known construction. (Not shown.) The shaft is allowed to escape step by step by making and breaking the circuit in the main line L, containing electro-magnet m, which controls the escapement e f. In the main line L is also an electro-magnet, on, having a softiron core wound with insulated wire, in the usual manner, to a higher resistance than mag- 8 5 net wt; or the iron core may be covered with a tube of brass, which will cause it to magnetize much slower than an ordinary magnet of the same size and resistance. This magnet is provided with an armature and bar, (I, hav- 9o ing a hooked termination, d. 1

To the type-wheel shaft is firmly fixed a radially -projecting arm, a, in the plane of armature-bar d, andcapablc of locking with hook d, by which ,means the type-wheel shaft is held at rest. Normally hook d is held in the path of rotation of arm a by a spiral retracting-spring, s. The position of arm a upon shaft 1) is such that when a is locked with d the type-wheel will be at unison.

The transmitter may be of the well-known m, and thus move the armature-bar (I out of the path of arm a. The transmitter may be driven by any suitable motor, and a key-board may be provided with means for stoppin'g'the transmitter at any desired point. Instead, however, of widening the conducting-section, as shown at 25, means maybe provided for halting the transmitter for an. interval sufficient 'to prolong the pulsation.

In a second main line, L we have shown means for printing from either type-wheel at pleasure,which consists of an impression-pad movable upon its bearings into the plane of rotation of either type-wheel, and an electromagnet having an armature-bar carrying a pivoted T-lever, the long arm of which is placed between two disks on the arbor of the "impression-pad. Two radial pins project from the type-wheel shaft in different radial planes, their outer ends respectively being capable of engaging the outer ends of the shorter arm of the T-lever.

To shift the pad from one'wheelto the other, the type-wheel shaft is rotated into such a po sition that the proper radial arm will be immediately over the one end of the T-lever, and an impulse is sent through the printing-circuit, thus tilting the T-lever and moving the impressioirpad as desired. The type-wheel is then rotated to present the desired character to the pad, and an impression is taken in the usual manner.

Means for feeding the paper after each impression, which are well known, may be provided.

we are aware that Bunnell employs a typewheel magnet which is excited and operated by short impulses, and a neutral magnet which is operated by a stronger and increased impulse for effecting unison. Specifieally,however, Bunnell, by a prolonged impulse, releases the escapement-pallets and permits an escapement-wheel, to which the type-wheel isrigidly attached, to move freely to the unison-point.

Our invention contemplates the use of a unison-stop which shall only release the typewheel shaft when it has arrived at the unison position.

In our apparatus means for permitting a free rotation of the typewheel shaft is entirely omitted.

Having described our invention, what we 1.
